SPEIFICATIGNforming part of Letters Patent No. 314,974, dated March 31,1885.

Application tiled April 95,1884. (No model.)

To ctZZ whom t may concern,.-

Be it known that I, ROBERT S. NOBLE, a citizen of the United States, residing at West Bay Oity, in the county of Bay and State of Mlchigainhave invented a new and useful Vindow-Sash Fastener, of which the Afollowing is a specification.

My invention relates to improvements Ain window-fasteners in which a movable camlever and bolt and spring operate in conjunction with rigid studs attached to a stationary plate which is firmly secured to a windowsash; and the objects of myinvention are,iirst, to produce a window-fastener which will hold the sash firmly in any desired position; second, to afford means of leaving the sash entirely free to be moved up or down; and, third, to provide a means of securely locking automatically a window-sash when it shall be closed. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in Which- Figure l is a front view of a portion of a sash with my invention attached thereto with the cani-lever and bolt in position for holding the sash opened. Fig. 2 is a back view of the same. Fig.` 3 is a side view'of the same from the edge of the sash. Fig.4 is a front view of my invention, showing the position of the cam-lever and bolt when the sash is free to move, also the mechanism for tripping the cam to lock automatically. Fig. 5 is a back view of the same. Fig. 6 is a front view of the face-plate and studs, and showing the slot through which the screw is passed for securing the cam and lever to the bolt. Fig. 7 shows the device when the sash is locke-d. Fig. 8 is a back view of the same. Fig. 9 is an end view of the same opposite to that of Fig. 3. Fig. 10 is a sectional view at x x in Fig. 4.

Similar letters referto similar parts throughout the several views.

a represents a portion of a window-sash, and b a part of thejamb of a window-casing, and c is the inside stop for holding the sash in place.

d is a plate of a suitable size, which is attached to the front side of the sash, and provided with the portions r and s,turned at right angles with the plate d, and provided with suitable holes to receive the bolt Z.

e is acam which is attached to the face-plate (Z by means of the screw p, which 'passes through the slot L in the face-plate andl into the bolt Z, and is firmly secured thereto.

f is a lever which is attached to and used to operate the cam c.

g is a stud which face-plate d in such a position as to engage with the cam @when the lever f is movedover toward the jamb.

L is a stud firmly secured to the face-plate d nea'r the stop c, and adaptedv to engage with the recess t in the cam ewhen the lever is pressed away from the jamb. The cam e is also provided near the recess twith the lug n,

is attached rigidly to theV which, when the recess t is engaged with the stud i, is adapted to engage with the spring Za, which is attached to the stop c, as shown in Fig. 4.

m is a spring which is coiled around a reduced portion of the bolt Z, one end of the spring bearing against a shoulder on the l olt, whilethe opposite end bears against a portion, r, of the face/plate d, and is adapted to hold the bolt Z against the j amb Z) or into the notch o.

lVhen the sash is open to the required position,the lever f is moved away from the j amb, which causes the cam e to engage with the stud g, and serves to press the end of the bolt i iirmly against the jamb b, and thereby hold the sash rmly in position, as shown in Fig.l.

To raise or lower the sasli,thelever f is moved toward the janib and the cam is engaged with the stud ,and the boltZ moved backward and there' held by the stud i catching into the recess t, when the sash is free to be moved up or down, as may be seen inFig. 4.

k is a spring-catch, the spring end of which is securely fastened to the stop c, while the other end, forming the catch, projects a short distance beyond the stop c, the face of one side of the projecting catch being at right angles with the stop c, while the opposite side or face is sloping, and for the upper sash is located just below the notch o,with the sloping face of the catch above, as shown in Fig. 4.

When the bolt Z is held back, as described, by the stud t catching into the recess t while the sash is being raised for closing, the projecting lugw catches upon the lower or straight side of the catch Zr, which serves to disengage ICO the recess t from the stud i, and allows the spring m to press the bolt Z against the jamb b, and, as the sash is farther raised, the bolt Z passes into the notch o in the jamb b, and the sash is securely locked in position.

To lower the sash,th eleverf is drawn away from the jamb b, and the recess t is engaged with the stud z' and holds the bolt Z back,leav ing-the sash free to be moved downward, and as the under or opposite side of the lug n comes in contact with the upper or sloping side of the projecting catch 7a the catch lc, recedes and allows the lug u to pass by without disengaging the recess t from the stud i, which allows the sash to be moved freely until it reaches any desired position, when the lever f and cam e are operated and the sash secured.

What I claim, and desire to secure by Letters Patent, is-

l. In a window-sash fastener, the faceplate d, provided with the slot h and the studs i and g, the bolt Z,and spring m, in combination with the came, provided with the lever f, and secured to the bolt Z by the screw p passing through the sloth, and adapted to engage with 2 5 the stud Z for moving the boltZ back and holding it free from thejarnb b and to engage with the stud g for pressing the end of the bolt Z firmly against the jamlo for holding the sash in a desired position, substantially as described 3o and shown.

2. In an automatic sash-fastener, the plate d, having the studs t' and g and slot lz., the bolt Z, provided with the spring m, the cam e, provided With the lever f, the recess t, and the projecting lug n, in combination with the spring-catch k, located and arranged to operate substantially as described,and for the purpose specied.
